RE: [wsrf] Issue: Finding WSDL from an EPR

["David Orchard" <dorchard@bea.com>]

Reducing dependencies as the critera for problem solving means re-inventing the wheel when potentially adequate technologies are not used to solve such problems.  One of my pet peeves is the continual re-invention of the wheel that people want to do.

Is there something technically inferior in ws-metadatexchange for this problem space?

Cheers,
Dave
